It raises and combines collective effect.
Further, the flume wall (1) in upstream transition section (2) is arranged by bracket (5) for the indicator water gage (6)
Top.
In actual use, water flow makes the sediment settlement in water body by filter plate (7), so that water body is more limpid and flows
Speed slows down, and reaches waterpower slope surface (8) by the water flow of filter plate (7), due to being obliquely installed for waterpower slope surface (8), rises to water flow
The effect buffered to one, and process is elongated, so that water flow more smoothly enters in flume, at this point, flume upstream
The indicator water gage (6) of changeover portion (2) setting can accurately obtain real time water level data, and be transmitted waterlevel data by gateway
To cloud platform, cloud platform flow rate calculation formula can calculate automatically data on flows according to real-time waterlevel data.
Flow rate calculation formula is as follows:
Q=C1*Hn1
C1=K1*W1.025
Wherein, Q: crossing slot flow, and unit is cubic meters per second (m3/ s)；
C1: free flow coefficient；
H: the upstream depth of water in slot, unit are rice (m)；
n1: free stream index is influenced by flute length；
K1: the flute length coefficient of free flow is influenced by flute length；
W: throat opening, unit are rice (m)；
The upstream depth of water (H) monitors and is transmitted to the data of cloud platform by indicator water gage (6) in slot in above-mentioned formula,
Its surplus is design parameter of the rectangle without larynx flume, and the setting due to indicator water gage (6) is to realize flume
The real-time monitoring of water level calculates flow by cloud platform automatically, meets the demand of irrigated area automation and modernization.
Compared with prior art, the utility model efficiently solves rectangle without the survey as caused by sediment siltation of larynx flume
The inaccurate problem of water, channel bottom are arranged using U-shaped channel, and channel destroying problem caused by frost heave can be effectively relieved.It solves
Personal monitoring's water gauge error is big, cannot obtain the problem of the information such as water level and flow in real time, automatically, it is tight to alleviate human resources
, and data precision is reliable, has a wide range of application, is practical, meets agricultural modernization, information-based demand.
